Abstract

PURPOSE:To enable access to an additional processor from a maintenance panel by sending a signal, which is equivalent to a control signal sent from CPU to an interface device to control the additional processor, from the maintenance panel to the interface device via CPU. CONSTITUTION:To CPU1 of a data processing system, memory device 2 and additional processor 5 are connected via interface device 3, and to CPU1, maintenance console panel 4 provided newly with switches 19 and 20 is connected via address bus 21 and data bus 22. In CPU1, switch signals of switches 19 and 20 are ORed by OR gates 15 and 16 with the output of microinstruction decoder 14 and that of selective signal part 13, and an address is supplied to address decoder 18 of device 3. Then, access to additional processor 5 from maintenance panel 4 is attained without providing a new maintenance panel dedicated to additional processor 5.
